Hello, I build D3.js charts for living since a year, I have developed Complex charts which handle millions of data, in one year I have built Capability plot with multiple charts merged in it, heat maps with customization like highlighting the data points and showing them separately and multiple charts which seperate themselves based on different data. Whatever chart you are looking at I can build it for you and customize it the way you want it. please send your requirement
Regards,
Suhas
